riroroenarnio-PRINTING DEVICE.

Application filed January 24, 1921. `Serial No. 439,594.l

` vices; and I do declare the following to be a full, clear, and exact description. of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.y

My invention'relates to photography and more particularly to the printing lof pic-- tures from iilms or plates, the principal object of the invention being to provide a simple and inexpensive, yet a highly eiiicient and desirable device for rapidly printing a plurality of duplicate pictures on a singlestrip of sensitized material, novel provision being made for holding a film strip having different images, so that any of thesev images may be exposed and a number of pictures printed therefrom.

A further object of the invention is to make novel provision whereby a border for one picture is printed simultaneously with the printing ofthe next adjacent picture.

With the foregoing in view, the invention resides in the novel construction and arrangement of parts hereinafter described and claimed, the descriptive matter being supplemented by the accompanyingfdrawmos.

Figure l is a perspective 4view of a photographic printing device constructed in accordance with my invention,'showing a film clamped in place preparatory to positionin@r a strip of sensitized paper thereover.

tFigure 2 is a duplicate of Fig. l with the exception that it illustrates the sensitized strip clamped in place upon. the film.

Figure 3 is a detail perspective view illustrating more clearly the plate which makes possible the simultaneous printing of one picture and the border for the `next adjacent picture.

Fifure 4 is a vertical sectional view picture strip printed by the device.

In the drawings above briefly described,

the numeral l designates an appropriate lamp box inwhich is `located an electric v light 2 controlled by means of an appropriate switch?) which is preferably located on the inclined front end of the box, which end is shown consisting of a xed lower section 4 and an upwardly swinging hinged section 5, vthe ven'dsof the latter being pref-` erably extended beyond the section 4 as indicated. at 6, so as to forni convenient hand grips by means of which said section 5 mayl be elevated whenever desired. The sectionor board' 5' forms a support for alilrn strip 7 or other negative and is provided with an opening 8 `through vwhich the rays of light from the lamp 2'1nay shine through the film onto a strip9 of printing paper or othery sensitized material. .As shown clearly 4in Figs. l, 2, 3 and 5, the opening 8 extends laterally beyond the film path, this provision `being made for a purpose to appear below. f i A For the purpose of guiding the film strip 7 and securing it in place when it is longiv is adapted to be successively advanced across said lm so that a number of pictures may be printed on said strip 9, fromthe same image. 'To guide `the strip 9 While it is being fed in this manner, I pro-vide any appropriate means `which is here shown in the `form of a rib or ledge 12 extending preferably throughout `the 'length-Of theboard 5, y

and positioned adjacentl 'the lower edge of the Opening 8, `said ledge and lboard being preferably provided with indicatingv marks lwliich are useful ,inv shifting thestrip 9 theproper amount afterfthe printing of each picture.

F or' holding the strips and 7y tightl against each other and in tight Contact Wit a glass plate l4xwhich covers the opening 8,

I provide a` felt' lined clamping memberlwhich at l5 is pivotally .mounted on the board 5 so as to swing downwardly over the crossed portion of the two strips, said member being adapted to be held in place` by hand while the light 2 is illuminated to print upon the sensitized strip 9.

As above set forth, the opening 8 extends laterally from the film path and this opening is covered by the glass plate 14.-. This plate is suitably plated throughout the greater part of its area so as to render it non-transparent. It is provided however with a transparent area 1G through which Jche rays from the lamp 2 are directed for passage through the film 7 to print a picture on the strip 9, said film being guided accurately over the area 16 by means of a notch 17 in the rib or ledge 12, through which notch the film. extends as shown. The portion of the plate 14- at the side of the film path is provided with one or more transparent areas 18 so arranged as to permit rays of light from the lamp 2 to pass therethrough and thereby print a border for one picture, while another picture is being printed on the strip 9. If the area or areas 18 surrounded the area 16, the border would bevery dim at the top and bottom of the picture and sharp along the vertical sides thereof, due to the fact that at said'top and bottom, the rays would be'forced to pass through both of the plate 14; at the film strip, whereas at the sides, the rays would travel only through the plate. llt is there- 'fore of great A'advantage to employ the arrangement shown for printing one picture and simultaneously printing a border for the next adjacent picture.

In operation, a film strip 7 or other negative having a plurality of different images thereon, is passed through the notch 17 and clips lO and after adjusting to position one of the images over the area 16, is held by said clips. vA strip 9 of printing paper or other sensitized material is now placed over the portion of' the glass 14C which projects beyond the film. This having been done, the clamping member 15 is swung downwardly and held by hand while the highimweredV lamp 2 is momentarily illuminated. The rays from the lamp are projected through the area or areas 18 and thus print a border onthe strip 9. When the current is turned off from the lamp 2, the strip 9 is fed inwardly across the film strip 7 so that the previously printed border is positioned around the image on the film. This having been done, the two strips 7 and 9 are properly held against each other by the clamping member 15 and the lamp 2 is again illuminated. This causes a picture to` be printed on the strip 9 within the border previously made, and alsol causes the simultaneous printing of a border for the next adjacent picture. This operation is repeated successively until the desired number of pictures have been printed and if the row of pictures is to extend entirely from end to end of the strip 9, the last printing operation will of course form a picture in the previously formed border.

Since excellent results have been obtained from the several details shown and described, these details may be followed if desired. l wish it understood however that within the scope otl the invention as claimed, numerous changes may be made. Furthermore, although I intend in most instances to employ a film strip, it will be understood that an elongated glass negative could be substituted. Furthermore, although the strip 9 is in most cases formed of ordinary printing paper, it might be in the form of an elongated sensitized plate.

I claim:

1. A photographic printing device comprising a supporting board having an opening and a transparent plate thereover, film hold-ing clips on said board at opposite sides of said opening and adapted to hold a film in place on said plate, a rib on said board extending along one of said sides of the o opening and adapted to guide a strip of sensitized material across the film, and a clamping member pivotally mounted on said board to be swung over the crossed portion oi the film and strip to hold them in place on said plate while directing light rays through the latter.

2. A photographic printing device comprising a supporting plate for a film and a strip of sensitized material, said plate having a transparent portion through which light rays may pass to the film to print a picture on the sensitized strip, said plate also having at one side of said transparent area, a transparent portion adapted to print a border for the next picture while one picture is being printed.

3. A photographic printing device comprising a pla-te on which a film. is adapted to rest, and guiding means along which a strip of sensitized material is adapted to be successively advanced across the film, said plate having a transparent area through which light rays from the film may pass to print a picture on the sensitized strip, said plate being additionally provided at one side of said transparent area, with a transparent portion adapted to print a border for the next picture while one picture is being printed.

4. A structure as specified in claim 1; said plate having a transparent area located on the film path and being additionally provided at a point spaced laterally from said film path, with a transparent portion adapted to print a border on the sensitized. strip.

In testimony whereof I have hereunto set my hand.
